How to block spam in Outlook Express.

Some people are having problems Blocking Spam in Outlook Express. Thanks Jorge. Steve 

To block messages from a sender or domain:

1. In your Inbox folder or in the list of messages in a newsgroup, click the message from the sender that you want to block.
2. On the Message menu, click Block Sender.

NOTE: To use the Block Senders feature in Outlook Express, your e-mail server must be a Post Office Protocol 3 (POP3) server. If your server is a Hypertext Transfer Protocol (HTTP) server, such as Hotmail, or an Internet Message Access Protocol (IMAP) server, this feature is not applied.
